Margaret Mary Street (1907-1993) was born in Toronto and received a B.A. from the University of Manitoba in 1928. In 1936, she graduated from the Royal Victoria Hospital School and, in 1942, she earned her Masters degree in Nursing from McGill University. She then taught nursing in Montreal, Winnipeg and Victoria prior to coming to UBC in 1952 for one year. After eight years as associate director of nursing in Calgary, Street earned a M.Sc. in Nursing Service Administration from Boston University. In 1960, she returned to UBC where she remained until her retirement in 1972.
As a personal commitment to help mark the golden jubilee of UBC's School of Nursing, Street undertook a project to write a biography of Ethel Johns. Published in 1973, "Watch-Fires on the Mountains: The Life and Writings of Ethel Johns", recounted the career of Johns (1879-1968), one of Canada's pioneer nurses who influenced the development of the profession and also served as the first director of nursing at UBC.
